To all whom il may concern:
Be it known that l, GEORGE HALE llimuooli, a eiti= zen ol the United States, residing al, 'lauutou, county of Bristol7 Stille of Illussaehusetta, have invented a cer- Lain new and useful improvementiu Meihod of Producing Castings, ol which the following is a speeitil'ution reference heine had therein to Vthe aeconi )an 'in 7 i n n 'compared with the area, of their surfaces, such for exuniple as ornamentul hron/.e plaques or similar articles. Such articles are usually malle from sheet nietnl on aeeouni of the impossibility.' of producing y. uctieal castinffi. l. have (linen-tiered thai; phosphorus applied to l.. l metal while the latter ie in e. molten suite in the mold will improve its fluidity or flew, thereby Causing it. lo proi'lerlg.' and completely-lill the mold.
